I'm in the midst of converting and running the old 3E supermodule Return to the Temple of Elemental Evil. Most of it straightforward, but I'd like some input on one thing, converting the old Force Domain a lot of the Tharizdun clerics use.
The spell list is OK, but I'm pondering the granted powers. The old one they used to get was the ability, once per day, to roll for damage twice and take the higher result. I'm thinking of adapting that ability to work more like the "Bit of Luck" ability from the Luck domain. So, 3+Wis Mod/day they could touch someone and grant them rerolls on damage for the next round. I could call it "Force of Destruction". For the 8th level power, I was thinking of stealing the Protection domain power to grant deflection bonuses to people in range. Instead of elemental resistance as well, it would grant a resistance to Force effects. There is no precedent for something like that, but I figured it would be cool for a weird Tharizdun thing. I could call it "Force Deflection".
Does this sound reasonable?
